The utility model content
The purpose of the utility model is to provide a kind of with oil sample drainage to lower, the vacuum sampling device easily of taking a sample for the deficiency that solves above-mentioned prior art.
In order to achieve the above object; A kind of drainage type vacuum sampling device that the utility model designed; Comprise a shell, it is characterized in that described shell is pierced by a hollow piston post, the hollow space of said piston boit constitutes the Oil Guide passage; One end of said piston boit is provided with the stopple coupon of opening; The other end of piston boit is communicated with an oil guide pipe, and the sampling switch that be equipped with sample cock and match with sample cock at the mouth of pipe place of said oil guide pipe, described shell are spirally connected and one can promote the piston boit knob of displacement forward.Shell is with after the equipment that needs sampling is connected, and rotary knob is pushed ahead piston boit, the stopple coupon access arrangement get hydraulic fluid port, oil sample flow to oil guide pipe, when needing to detect oil sample, opens sampling switch and can gather oil sample.This sampler is easy for installation, and with the lower of oil sample drainage to convenient sampling, the workload that reduces a staff is increased work efficiency; And avoided the staff to climb and carried out the charged dangerous operation in high-altitude, guaranteed the safe distance of operation, safety, reliable; Sampler is not just splitting with after oil sample equipment to be checked is connected, directly control sampling switch when needing sampling and get final product, and has avoided contacting of oil sample and air, has guaranteed the reliability of result of laboratory test.
As preferably, described piston boit is provided with a convexity, and described knob is pierced and be screwed onto the outer wall of shell by piston boit; The interior round platform wall of knob is inconsistent with a protruding side; When reliable transmission, knob push piston boit, piston boit is positioned; Avoid piston boit back and forth displacement cause oil sample to contact with air, influence result of laboratory test.
As preferably, the opposite side of said convexity is inconsistent through O-ring seal and shell, guarantees sealing effectiveness, avoids the air entering.
As preferably, described outer shell outer wall is provided with the spacing block set that matches with knob, avoids knob excessively to advance the damage that causes sampler.
As preferably, be provided with O-ring seal between described outer casing inner wall and the piston boit outer wall, further guarantee sealing effectiveness.
As preferably, described piston boit stage casing outer wall is provided with groove, and O-ring seal is located in the groove, good sealing effect.
As preferably, described stopple coupon and piston boit are spirally connected, and stopple coupon or piston boit can be changed as required, and versatility is high.
As preferably, described shell forms thread segment after leaning on sample tap end undergauge, and the thread segment outer wall has screw thread and the inboard is provided with O-ring seal; Thread segment is used for being connected with oil sample equipment to be checked; Be threaded and be convenient to control shift length, with the effect that accurately moves before and after reaching, easy to operate.
Described shell is a stepped construction, leans on the size of stopple coupon side minimum, seal more reliably, avoids seepage oily.
A kind of drainage type vacuum sampling device that the utility model obtains, easy for installation, with the lower of oil sample drainage to convenient sampling, the workload that reduces a staff is increased work efficiency; And avoided the staff to climb and carried out the charged dangerous operation in high-altitude, guaranteed the safe distance of operation, safety, reliable; Sampler is not just splitting with after oil sample equipment to be checked is connected, directly control sampling switch when needing sampling and get final product, and has avoided contacting of oil sample and air, has guaranteed the reliability of result of laboratory test.
